Purpose : The purpose of this study was to study the effects of resistance training combined with different attentional focus on thigh muscle size and muscle strengthMethods : Twenty – four untrained men college (age 18 – 30 years) were randomly assigned to an internal focus combined with resistance training (n=8), or an external focus combined with resistance training (n=8), or a common resistance training (control) (n=8). All three groups performed a same exercise (machine leg extension) with 3 time per week for 6 weeks. Quadriceps muscle cross-sectional area, Isometric knee extension strength and 1RM knee extension strength were measured before and after training. Electromyography (EMG) were assessed in training week 1 and week 6. Data were analysed using Two-factor Mixed-design ANOVA with repeated measure. A level of significant was set at p-value < .05.Results : After 6 weeks of training, all three groups show similarly significant increase in Quadriceps muscle cross-sectional area, Isometric knee extension strength and 1RM knee extension strength, with no differences between groups. There was significant higher for EMG value in internal focus group than external focus group and control group.Conclusion : Resistance training combined with internal focus was not effective in increasing thigh muscle size and muscle strength when compared with external focus and common resistance training. If attempting to maximize muscle activation, an internal focus would seem to be a better choir.
